Pro-source 8357503811PRO Oil Resistant Air Hose 50 Ft

Product Description

The PRO-SOURCE 8357503811PRO is a heavy-duty rubber air hose built for compressed air systems in shops, service bays, and industrial environments. Constructed from oil-resistant rubber, it handles working pressures up to 300 psi and operates across a temperature range of -22 degrees F to 158 degrees F. The hose measures 3/8 inch inside diameter and runs 50 feet in length, making it a practical choice for general-purpose air tool use. Male NPT fittings on both ends allow direct connection to standard air supply lines and tools. Licensed HVAC technicians, plumbers, mechanics, and general tradespeople are the typical installers and users of this hose.

This hose is suited for residential and commercial service work where a durable, oil-resistant air supply line is needed. The 3/8 inch ID supports adequate airflow for common pneumatic tools including impact wrenches, ratchets, and air drills. The 50-foot length provides reach across most service bays and job sites without requiring an extension. Red color aids visibility on busy work surfaces. MNPT x MNPT end connections are compatible with standard air fittings and quick-connect adapters widely used in the trade.

Compatibility

Designed as a general-purpose replacement or new-installation air hose compatible with standard compressed air systems using 1/4 inch MNPT fittings and operating within the rated pressure and temperature limits.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with compressed air systems. Depressurize the air supply line completely before connecting or disconnecting the hose. Inspect fittings for thread condition and apply appropriate thread sealant to MNPT connections to prevent leaks. Do not exceed the 300 psi working pressure rating or operate outside the rated temperature range.
